What the blazes is this?🤔

I was given a couple of crates of RC goodies, this was in there. I assume it’s some sort of dinosaur part for a tx or rx . Can’t find it online. Just curious.

Those were for old transmitters. Each crystal was a different signal.

Wow.
That is from Radio's of the 1990's. Obsolete AM frequency crystals.
Maybe someone on Ebay needs them for an old Jr radio.
Back in the day, to race at the track you needed spare frequencies to race, because of overlapping frequencies. And Racers could not compete on same freqs obviously. One crystal for the Rx and one for the radio. Matched pairs.

OMG! Antiques roadshow?
$8000 and its yours

Red crystals are fastest

You used to need a few sets of those for different channels in the case someone was running the same as yours.

You guys are aging yourselves

I still have a few different colored crystals and a transmitter for them. Always funny when you asked your buddies what color you running today.

I still have a radio that uses those. Actually had one come loose on my nitro buggy and it took off full bore. Ran into my neighbors house and started doing a smokey burnout.

Okay, price drop, $7000

The jr. racing tx was the bomb for a rtr. I could run 4 of my nitro cars with the same tx, and it was digital

I’ve seen too many cars ghost away into walls, streets and get run over, crowds ETC because someone showed up to a race, or bash spot and didn’t ask what flavors others were running before turning their on.. I’ve seen brawls over flattened cars before. Big time NO NO not to ask flavors first back then!!

 

[JoshHefnerX]

well, way back... some people had colored flags to show what they were running.

Price drop, $5000 it’s yours

At the track, the race director wanted everyone to quarantine their radios in one area. And you had to use a close pin clipped to your radio antenna with the frequency number whether for AM or FM bands. So others knew what channel you were on.
No radios were ever at your pit table. Once you paid your race fee, the radio was collected from you. The only time you held your radio was on the driver stand. Strict rule. Even if it was a practice day. Sometimes you waited for drivers to leave the track.
But back then, if you got 5-8 minutes out of your 7.2v Nicads running modified brushed motors, you were lucky.
